In another alternate embodiment, the lid assembly 324 can include a lid coupling mechanism that selectively couples the first and second lid members 326, 328 such that the first and second lid members 326, 328 are collectively operable between open and closed positions.

Referring again to the illustrated embodiment, as best illustrated in FIGS. 8A and 11-18, the cooking appliance kit 10 includes a cooking vessel 14 and a selectively operable arcuate dividing wall 32. The cooking vessel 14 is configured to be selectively inserted into the heating cavity 16 and includes first and second rounded ends 18, 20. The intermediate necked portion 22 is defined by the intersection of the first and second rounded ends 18, 20. Moreover, the first and second rounded ends 18, 20 and the intermediate necked portion 22 cooperatively define the first and second wells 24, 26 that at least partially intersect. The cooking vessel 14 can be made of heat conductive materials that include, but are not limited to glass, ceramic materials, and the like.

As illustrated in FIG. 12, the first and second rounded ends 18, 20 and the intermediate necked portion 22 define a substantially leminiscate cooking vessel volume 350 and a substantially leminiscate cooking vessel base 352. The cooking vessel base 352 is configured to rest on the first and second distinct heater plates 28, 30 proximate the leminiscate base 272 of the heating cavity wall 192 (shown in FIG. 10). In this manner, the first and second distinct heater plates 28, 30 provide selective independent heating to the first and second wells 24, 26 of the cooking vessel 14, respectively, and provide selective thermal communication between the first and second distinct heater plates 28, 30 and the cooking vessel volume 350.

Referring again to FIGS. 2, 8, 8A, and 9, the first and second rounded ends 18, 20 of the cooking vessel 14 can be configured to selectively engage at least a portion of the heating cavity wall 192. Upper ends 230 of the first and second rounded ends 18, 20 and the intermediate neck portion define a rim 236 of the cooking vessel 14. The rim 236 can include a flared rim flange 348 that extends outwardly from the first and second wells 24, 26. The flared rim flange 348 can be configured to selectively extend over at least a portion of the cavity wall rim 290 of the heating cavity wall 192.

As illustrated in FIGS. 8A and 11-13, in various embodiments, the intermediate necked portion 22 of the cooking vessel 14 is disposed within the cooking vessel volume 350 proximate the intersection of the first and second wells 24, 26. The first and second rounded ends 18, 20 include a substantially oblong outer surface 386 of the cooking vessel. The first and second round ends 18, 20 and the intermediate necked portion 22 define a leminiscate cooking vessel volume 350.

As shown in FIGS. 12 and 18, the cooking vessel base 352 can include a perimeter fillet 354 that extends from a perimeter of the cooking vessel base 352 and couples the cooking vessel base 352 to the first and second rounded ends 18, 20 of the cooking vessel 14. The perimeter fillet 354 substantially rounds the cooking vessel volume 350 between the cooking vessel base 352 and the first and second rounded ends 18, 20 and substantially directs the contents of the cooking vessel volume 350 toward the respective first and second well centers 356, 358 of the first and second wells 24, 26.

Also, as illustrated in FIGS. 8A and 11-13, the first and second wells 24, 26 substantially define frusto-conical volumes that at least partially intersect at the intermediate necked portion 22. As will be further described below, the first and second wells 24, 26 define first and second mixing zones 370, 372, respectively. The intersection of the first and second wells 24, 26 further defines an intersection 368 of the first and second mixing zones 370, 372, wherein food contents contained within the cooking vessel volume 350 can be cooperatively mixed within the first and second mixing zones 370, 372, thereby increasing the mixing ability of the cooking appliance kit 10 within each of the first and second wells 24, 26, and the cooking vessel volume 350 as a whole. The first and second mixing zones 370, 372 can intersect in the area defined by the intermediate necked portion 22. In an alternate embodiment, the walls of the vessel 14 include a stepped configuration in order to accommodate, accept or rest cooking accessory inserts, such as steaming baskets, raised warming plates for bread, etc.

Referring now to FIGS. 8A and 13-18, another aspect of the cooking appliance kit 10 includes an arcuate dividing wall 32 that is selectively removable from the cooking vessel 14. The arcuate dividing wall 32 is defined by first and second side edges 390, 392, a bottom edge 394 and a concave surface 388 defining a curvature substantially similar to that of the first and second wells 24, 26. The first and second side edges 390, 392 and the bottom edge 394 of the arcuate wall define an engagement surface 396 configured to be selectively received by the intermediate necked portion 22 of the cooking vessel 14. The arcuate dividing wall 32 can include first and second engagement members 398, 400 that extend from at least a portion of the first and second side edges 390, 392, respectively. First and second notches 402, 404 can be disposed in first and second sides 406, 408 of the intermediate necked portion 22 of the cooking vessel 14, respectively. The first and second notches 402, 404 are configured to selectively receive the first and second engagement members 398, 400. It should be understood that the first notch 402 can receive the first and second engagement members 398, 400 wherein the second notch 404 would receive the other of the first and second engagement members 398, 400. In this manner, the concave surface 388 of the arcuate dividing wall 32 can be oriented towards either the first well 24 or the second well 26.

As illustrated in FIG. 13, the first and second engagement members 398, 400 of the arcuate dividing wall 32 and the first and second notches 402, 404 of the cooking vessel 14 have a substantially trapezoidal lateral cross section. It should be understood that the shape and size of the notches 402, 404 and matingly configured engagement members 398, 400 can vary. By way of explanation, and not limitation, the engagement members 398, 400 can have an arcuate or orthogonal shape or a combination of arcuate and orthogonal shapes. It should also be understood, that the shape of the notches 402, 404 can be different from the shape of the engagement members 398, 400 so long as the notches 402, 404 are configured to receive the first and second engagement members 398, 400. In this manner, the shape of the notches 402, 404 and the shape of the engagement members 398, 400 can differ without decreasing the efficiency or usefulness of the cooking appliance kit 10.

Referring again to the illustrated embodiment, as illustrated in FIGS. 13 and 17, one or more gaskets 420 can be disposed on at least a portion of the engagement surface 396. The one or more gaskets 420 run along the engagement surface 396 and substantially follow the curvature of the concave surface 388 of the arcuate dividing wall 32. In alternate embodiments, the gasket 420 is made to be disposed only on the first and second side edges 390, 392 of the engagement surface 396. Alternatively, in other embodiments, the gasket 420 may be disposed only on the bottom edge 394 of the engagement surface 396.

As shown in FIGS. 13 and 17, the two or more gaskets 420 extend from the engagement surface 396 and are configured to be received by the intermediate necked portion 22 of the cooking vessel 14. It should be understood, that the number, shape and configuration of the one or more gaskets 420 can vary. By way of explanation, and not limitation, a single gasket 420 may be disposed on the engagement surface 396 where the gasket 420 defines a linear protrusion disposed along the engagement surface 396. In such an embodiment, the cross-sectional shape of the linear protrusion can include, but not be limited to, arcuate or rectilinear cross sections. In other alternate embodiments, the linear protrusion can include an extruded cavity within the length of the linear protrusion, wherein the coupling of the engagement surface 396 to the intermediate necked portion 22 of the cooking vessel 14 can compress the linear protrusion and define a seal between the first well 24 and the second well 26. Alternatively, the gasket 420 may take on a non-linear configuration.

Referring back to the illustrated embodiment, as shown in FIGS. 11-18, the arcuate dividing wall 32 is made of a substantially rigid material including, but not limited to, metals, plastics, rubberized materials, glass or ceramic material or other substantially rigid material. The material selected for the arcuate dividing wall 32 should also be of a material that can substantially withstand deformation when exposed to heat levels experienced in kitchen cooking appliances.

As illustrated in FIGS. 13 and 17, the illustrated gasket 420 is made of a substantially flexible material such as a rubberized material or plastic material that can create the desired seal between the first and second wells 24, 26 when the arcuate dividing wall 32 is engaged with the intermediate necked portion 22 of the cooking vessel 14. In addition, in certain embodiments, it is contemplated that the one or more gaskets 420 may be selectively removable from the engagement surface 396 of the arcuate dividing wall 32. In this embodiment, the engagement surface 396 can include a gasket receptacle portion 422 for receiving the one or more gaskets 420.

Alternatively, in other embodiments, the one or more gaskets 420 may be formed with and be an integral part of the arcuate dividing wall 32. In such an embodiment, it is preferred that the arcuate dividing wall 32 be made of a plastic or rubberized material so that the one or more gaskets 420 can create the desired selective seal between the arcuate dividing wall 32 and the cooking vessel 14.

Referring again to the illustrated embodiment, as shown in FIGS. 11, 13-15 and 18, the arcuate dividing wall 32 can also include a handle portion 424 disposed proximate an upper portion 426 of the arcuate dividing wall 32. The handle portion 424 can define an opening proximate an upper portion of the arcuate dividing wall 32. In alternate embodiments, the handle portion 424 can include a gripping ridge disposed proximate the upper portion 426 of the arcuate dividing wall 32. In other embodiments, the handle portion 424 can be a separate piece coupled proximate the upper portion 426 of the arcuate dividing wall 32.

As shown in the illustrated embodiment of FIGS. 8A, 13, 16 and 17, a convex surface 428 of the arcuate dividing wall 32 is configured to be substantially vertical, while the concave surface 388 is substantially slanted to match the frusto-conical curvature of the first and second wells 24, 26. The substantially vertical orientation of the convex surface 428 and the substantially slanted configuration of the concave surface 388 defines a tapered vertical cross-section of the arcuate dividing wall 32 having a narrow upper portion 426 and a widened bottom edge 394 that at least partially defines the engagement surface 396.

In an alternate embodiment, the first and second sides 406, 408 of the intermediate necked portion 22 can include an engagement mechanism for receiving the one more gaskets 420 of the arcuate dividing wall 32. In this embodiment, the engagement mechanism can include an engagement channel configured to receive the one or more gaskets 420 of the arcuate dividing wall 32, where the engagement channel can at least partially include the first and second notches 402, 404.

Alternatively, the engagement mechanism can include an engagement protuberance that extends from the first and second sides 406, 408 of the intermediate necked portion 22 where the engagement protuberance is configured to be received by the one more gaskets 420 of the arcuate dividing wall 32. In these alternate embodiments, the engagement channel and the engagement protuberance cooperatively engage at least a portion of the one or more gaskets 420 of the arcuate dividing wall 32. In this manner, the engagement mechanism slidably receives the arcuate dividing wall 32 and the one or more gaskets 420 of the arcuate dividing wall 32.

In the various embodiments that include the engagement channel, the cooking vessel 14 can include first and second filler members that can be slidably engaged into the engagement channels when the arcuate dividing wall 32 is selectively removed from the cooking vessel 14 to substantially prevent the contents of the cooking vessel 14 from entering the engagement channel.

Referring again to the illustrated embodiment, as shown in FIGS. 13 and 17, the first and second side edges 390, 392 of the arcuate dividing wall 32 are contoured thereby defining an engagement channel 430 that substantially matches the curvature of the first and second sides 406, 408 of the intermediate necked portion 22 of the cooking vessel 14 defining an engagement protuberance 432. In this manner, the engagement channel 420 of the arcuate dividing wall 32 slidably engages the engagement protuberance 432 of the intermediate necked portion 22 and defines a lateral interference connection between the first and second side edges 390, 392 of the arcuate dividing wall 32 and the first and second sides 406, 408 of the intermediate necked portion 22. This lateral interference connection substantially limits the lateral movement of the arcuate dividing wall 32 within the intermediate necked portion 22, while allowing the desired operable vertical movement of the arcuate dividing wall 32 within the intermediate necked portion 22.

As best illustrated in FIG. 12, the concave surface 388 of the arcuate dividing wall 32 and the second well 26 define a circular cooking zone 440 that is configured to define the second mixing zone 372. The convex surface 428 of the arcuate dividing wall 32 and the first well 24 define a crescent cooking zone 442, where the mixing functions of the cooking appliance kit 10 are substantially inoperable. As discussed above, the arcuate dividing wall 32 can be reversed such that the circular cooking zone 440 is at least partially defined by the first rounded end 18 and the crescent cooking zone 442 is at least partially defined by the second rounded end 20.

Also, as best illustrated in FIGS. 8-11, the flared rim flange 348 of the cooking vessel 14 includes first and second drive arm receptacles 450, 452. As will be more fully described below, the first and second drive arm receptacles 450, 452 are configured to receive the first and second drive arms 34, 36. The first and second drive arm receptacles 450, 452 are further configured to selectively orient the first drive arm 34 over the first well 24 and the second drive arm 36 over the second well 26. In alternate embodiments, the drive arms can be switched such that the first and second drive arm receptacles 450, 452 orient the first drive arm 34 over the second well 26 and the second drive arm 36 over the first well 24.

Additionally, as shown in FIGS. 8-11, the first and second drive arm receptacles 450, 452 are substantially rectangular to match the illustrated first and second drive arms 34, 36. In alternate embodiments, the drive arm receptacles 450, 452 and the drive arms can be rounded or have a different polygonal cross-sectional shape. The first and second drive arm receptacles 450, 452 and the first and second drive arms 34, 36 cooperate to define a substantially close fit to substantially prevent the contents of the cooking vessel 14 from escaping the cooking vessel 14 during use.

In other alternate embodiments, the drive arm receptacles 450, 452 can include receptacle gaskets that provide a seal between the first and second drive arms 34, 36 and the first and second drive arm receptacles 450, 452, respectively. Such a seal can further prevent liquids and other contents from escaping the cooking vessel 14 during cooking or mixing operations, or both.

Referring again to the illustrated embodiment, as best illustrated in FIGS. 10 and 19-22, the cooking appliance kit 10 includes a drive system 40 where the first and second drive arms 34, 36 are configured to be removably engaged and in operable communication with the drive system 40. The drive arms 34, 36 may be laterally pivotable relative to the cooking appliance kit 10. It is also contemplated that the drive arms 34, 36 could be independently upwardly pivotable. Further, the drive arms 34, 36 could be pivotable with the lid 46, such that when a user lifts the lid 46, the drive arms 34, 36 are also lifted. As shown in FIG. 19, the drive system 40 includes an electric motor 78 coupled with and in operable communication with a drive wheel 470. First and second idler wheels 472, 474 are disposed proximate the drive wheel 470. A plurality of wheel plates 476 are configured to secure the electric motor 78 and the idler wheels 472, 474 to the bottom panel 70 of the housing 12 within the secondary cavity 190. The wheel plates 476 are configured to secure the idler wheels 472, 474 and the drive wheel 470 to the bottom panel 70 and also allow for the rotational movement of the idler wheels 472, 474 and the drive wheel 470.

As shown in FIG. 19, a drive belt 478 is configured to engage the drive wheel 470 and the first and second idler wheels 472, 474, and define an operable communication between the drive wheel 470 and the first and second idler wheels 472, 474. First and second drive shafts 480, 482 extend from proximate ends 484 at the first and second idler wheels 472, 474 and are disposed co-linear with first and second rotational drive axes 486, 488 of the first and second idler wheels 472, 474, respectively, to distal ends 490 of the drive shafts 480, 482 proximate the first and second drive shaft openings 292, 294 of the top flange 38 of the heating cavity wall 192.

FIG. 19 also shows first and second drive receptacles 492, 494 that are coupled to distal ends 490 of the first and second drive shafts 480, 482 wherein the first and second drive receptacles 492, 494 extend through the first and second drive shaft openings 292, 294 (shown in FIG. 10) and are further configured to rotate within the first and second drive shaft openings 292, 294. First and second grommets 496, 498 are coupled to the first and second drive shaft openings 292, 294, respectively, and secure the first and second drive receptacles 492, 494 within the first and second drive shaft openings 292, 294 while allowing the rotational movement of the first and second drive receptacles 492, 494 within the first and second grommets 496, 498.

As further illustrated in FIG. 19, to allow for the desired rotational movement of the first and second drive receptacles 492, 494 within the first and second grommets 496, 498, the first and second drive receptacles 492, 494 can be coupled to an inner-facing surface 500 of the first and second grommets 496, 498 by a rotational sliding assembly that can include, without limitation, ball bearings, cylindrical bearings, lubricated members, or other rotationally slidable interface.

Also, as illustrated in FIGS. 19 and 22, the first and second drive arms 34, 36 each include an engagement gear 502 disposed at engagement ends 504 of the first and second drive arms 34, 36 that are configured to be selectively received by at least one of the first and second drive receptacles 492, 494. In this manner, each engagement gear 502 is in operable communication with at least one of the drive shafts 482, 484 and at least one of the idler wheels 472, 474, and the drive wheel 470 of the electric motor 78. Each drive arm 34, 36 contains a drive train 506 having a first train end 508 including the engagement gear 502 and a second train end 510 including a tool impeller 518 disposed at rotational ends 514 of the first and second drive arms 34, 36. A drive arm enclosure 516 is configured to receive the drive train 506 and secure the drive train 506 within the drive arm enclosure 516 by limiting the vertical and lateral movement of the drive train 506 within the drive arm enclosure 516 and also allowing the rotational movement of the drive train 506 such that the engagement gear 502 of the drive train 506 is in operable communication with the tool impeller 518 of the drive train 506.

As shown in FIGS. 19-22, each drive arm includes the first and second arm connectors 300, 302 disposed on the engagement end 504 of the first and second drive arms 34, 36. Each of the first and second arm connectors 300, 302 can include a tubular channel 530 extending vertically through the drive arm enclosure 516 proximate the engagement end 504 of the drive arms 34, 36 and a connecting assembly 532 having a connector end 534 extending upward through the tubular channel 530 to a knob end 536 for turning the connector end 534. The connector end 534 is configured to be received by the first and second drive arm interfaces 296, 298 in the top flange 38 of the heating cavity wall 192. As discussed above, the drive arms 34, 36 are configured to engage the drive system 40 and the top flange 38 of the heating cavity wall 192, such that the rotational ends 514 of the first and second drive arms 34, 36 are disposed over central axes of the first and second wells 24, 26 thereby defining the at least partially intersecting first and second mixing zones 370, 372 within the first and second wells 24, 26, respectively (shown in FIGS. 8 and 9).

As illustrated in FIGS. 19 and 20, first and second tool receptacles 542, 544 are disposed within the tool impellers 518 of the first and second drive arms 34, 36, respectively. The each tool impeller 518 of the first and second drive arms, 34, 36 defines first and second rotational mixing axes 546, 548 that are selectively and substantially intersect the first and second well centers 356, 358.

In alternate embodiments, the drive system 40 can include a drive gear coupled to the electrical motor and first and second idler gears coupled with and operably engaged with the drive gear where the first and second drive shafts 480, 482 are coupled with the idler gears and where the drive shafts 480, 482 define first and second rotational axes of the idler gears. This embodiment can operate without a drive belt 478 and can substantially prevent slippage between the drive belt 478 and the first and second idler gears and the drive gear.

Referring again to the illustrated embodiment of FIGS. 2 and 3, when the drive arms 34, 36 are selectively engaged with the housing 12 in the first and second drive interfaces 296, 298, the drive arms 34, 36 are received by the first and second drive arm receptacles 450, 452 of the flared rim flange 348 of the cooking vessel 14. In this manner, the first and second lid members 326, 328 are configured to define closed positions wherein the perimeters of the first and second lid members 326, 328 engage the flared rim flange 348 of the cooking vessel 14, without the first and second lid members 326, 328 interfering with the extension of the first and second drive arms 34, 36 over the first and second wells 24, 26, respectively.

As discussed above, and as further shown in FIG. 8, the selective engagement of the arcuate dividing wall 32 within the intermediate necked portion 22 defines a non-mixing area within the crescent cooking zone 442. In this configuration, the first or second drive arm 34, 36 that extends over the crescent cooking zone 442 can be selectively removed without interfering with the selectively engaged first or second drive arm 34, 36 coupled to the drive system 40 and that extends over the circular cooking zone 440 and defining one of the first and second mixing zones 370, 372 within the circular cooking zone 440.

It is contemplated that drive arm spacers can be inserted into at least one of the first and second drive arm receptacles 450, 452 when either the first drive arm 34, the second drive arm 36, or both are disengaged from the housing 12. The drive arm spacers can be configured to have a cross-sectional shape similar to that of the first and second drive arm receptacles 450, 452. In this manner, the drive arm spacers can selectively and substantially occupy the first and second drive arm receptacles 450, 452 to substantially prevent contents of the cooking vessel 14 from being expelled from the cooking vessel 14 through the first or second drive arm receptacles 450, 452 during use of the cooking appliance kit 10.

Referring back to the illustrated embodiments as shown in FIGS. 8-9 and 19-22, the stirring and flipping wands 42, 44 are configured for selective engagement within at least one of the first and second tool receptacles 542, 544. The selective engagement of the stirring and flipping wands 42, 44 further defines the first and second mixing zones 370, 372 (shown in FIG. 9). The selective engagement of the first and second drive arms 34, 36 to the drive system 40 further defines a mixing pattern of the first and second mixing zones 370, 372 wherein the first and second mixing zones 370, 372 at least partially intersect. The drive system 40 and the drive arms 34, 36 are further configured such that the rotation of the stirring or flipping wand 42, 44 connected to the first drive arm 34 does not interfere with the rotational movement of the stirring or flipping wand 42, 44 selectively coupled with the second drive arm 36 as the stirring and flipping wands 42, 44 rotate through the intermediate necked portion 22. In this manner, the first and second mixing zones 370, 372 are allowed to intersect without the stirring and flipping wands 42, 44 colliding during operation of a mixing function at the cooking appliance kits 10.

As illustrated in FIG. 19, the drive belt 478 couples to the drive wheel 470 and first and second idler wheels 472, 474 creates a common directional rotation of the first and second idler wheels 472, 474 thereby creating a common directional of rotation for the remainder of the drive system 40 and the drive arms 34, 36. In this manner, the stirring and flipping wands 42, 44 can be configured to rotate in the same direction (i.e. clockwise or counterclockwise).

In alternate embodiments, the drive system 40 and the drive arms 34, 36 can be configured to have opposite directional rotations such that one of the stirring or flipping wands 42, 44 will rotate clockwise and the other stirring or flipping wand 42, 44 will rotate counterclockwise. By way of explanation and not limitation, this opposite rotation can be accomplished by two drive belts where one drive belt couples the drive gear 470 to the first idler wheel 472 and the second drive belt couples the first idler wheel 472 to the second idler wheel 474. Alternatively, the configuration of the connection between the drive train 506 and the engagement gear 502 can create the opposite directional rotation of the first and second drive arms 34, 36.

In an alternate embodiment as shown in FIGS. 23 and 24, the drive system 40 is disposed within the lid assembly 324 such that when the lid 46 is in the closed position, the drive system 40 is disposed over the cooking vessel volume 350. A service channel 560 is disposed within the lid 46 and extends from the drive system 40 to the lid hinge 322 and into the housing 12, such that the drive system 40 can be coupled with the controls 122 to create a fluid communication between the drive system 40 and the controls 122 while still containing equipment and wiring within the service channel 560. A drive gear 562 and idler gears 564 are disposed on the underside 566 of the lid 46 in an operable communication with the motor 78. In this alternate configuration, no drive arms are present and the tool impellers 518 and tool receptacles 542, 544 are disposed at centers of the idler gears 564.

In addition, as shown in FIGS. 23 and 24, when the lid 46 is in the closed position, the idler gears 564 are disposed above the first and second wells 24, 26, respectively. The selective engagement of the stirring and flipping wands 42, 44 within the first and second tool receptacles 542, 544 defines the first and second mixing zones 370, 372 within the cooking vessel 14, wherein the first and second mixing zones 370, 372 at least partially intersect. The lid 46 and the service channel 560 cooperate to provide rotational movement of the lid 46 without interfering with the equipment and wiring disposed in the service channel 560.

Referring now to FIGS. 25-47 of the illustrated embodiment, another aspect of the cooking appliance kit 10, includes a mixing tool set including a pair of stirring wands 42, a pair of flipping wands 44, and a pair of combination wands 590 having stirring and flipping surfaces. Each of the stirring, flipping and combination wands 42, 44, 590 is configured for selective engagement in either of the first and second tool receptacles 542, 544 (FIGS. 19-20). In addition, each of the stirring, flipping and combination wands 42, 44, 590 includes a substantially cylindrical coupling arm 592 having a first end 596 configured to be received by either of the first or second tool receptacles 542, 544 (shown in FIGS. 19-20). The cylindrical coupling arm 592 further includes at least one orienting surface 594, that can include a flat surface along the length of the coupling arm 592 that is configured to orient the stirring, flipping and combination wands 42, 44, 590 within the tool receptacles 542, 544 such that the stirring, flipping and combination wands 42, 44, 590 are in a substantially vertical position.

As best illustrated in FIGS. 25-31, the stirring wand 42 includes a substantially vertical stirring portion 602 configured to slide along the first or second rounded ends 18, 20 of the cooking vessel 14 and a substantially horizontal stirring portion 604 configured to slidably rotate over the cooking vessel base 352 (shown in FIG. 12). The coupling arm 592 of the stirring wand 42 is coupled with an upper end 606 of the substantially vertical stirring portion 602 at a second end 600 of the coupling arm 592. The first end 596 of the coupling arm 592, as described above, is configured to engage the first or second tool receptacle 542, 544 (shown in FIGS. 19 and 20).

As shown in FIGS. 25-31, the substantially vertical stirring portion 602 includes a first tapered stirring surface 610 defined by a first pitch angle 612 located proximate the upper end 606 of the substantially vertical stirring portion 602 and a second pitch angle 614 located proximate a lower end 616 of the substantially vertical stirring portion. The first pitch angle 612 is greater than the second pitch angle 614. As illustrated, the first and second pitch angles 612, 614 are 60 degrees and 25 degrees, respectively. However, alternate configurations of the first and second pitch angles 612, 614 can be implemented, where the second pitch angle 614 is greater than or equal to the first pitch angle 612, without departing or interfering with the spirit of the illustrated embodiments.

Additionally, as illustrated in FIGS. 25-31, a second tapered stirring surface 618 is defined by the substantially horizontal stirring member 604. The second tapered stirring surface 618 includes a third pitch angle 620 proximate the lower end 616 of the substantially vertical stirring portion 602 defining a wand base 622 of the substantially horizontal stirring member 604, and a fourth pitch angle 624 proximate a wand tip 626 of the substantially horizontal stirring member 604. As illustrated, the third and fourth pitch angles 620, 624 are 28.7 degrees and 13.75 degrees, respectively. The third pitch angle 620 is greater than the fourth pitch angle 624. However, as discussed above, the configuration of the third and fourth pitch angles 620, 624 can vary such that the fourth pitch angle 624 is greater than or equal to the third pitch angle 620.

Also, as illustrated in FIGS. 8-9 and 25-31, the selective operable engagement of the stirring wands 42 within the first and second tool receptacles 542, 544 define the first and second mixing zones 370, 372 that at least partially intersect at the intermediate necked portion 22 (shown in FIG. 9).

In an alternate embodiment of the stirring wand 42, the coupling arm 592 includes a vertical support member that extends along the rotational axis of the tool impeller 518 and connects with the tip of the substantially horizontal stirring member. In this embodiment, the first end 596 of the coupling arm 592 engages at least one of the first and second tool receptacles 542, 544 in a substantially horizontal orientation. A curved realignment member extends from the first end 596 of the coupling arm 592 and is configured to realign at least a portion of the coupling arm 592 and the vertical supporting member of the coupling arm 592 within the rotational axis of the tool impeller 518 (similar to as shown in FIGS. 32-39).

Referring again to the illustrated embodiments as best shown in FIGS. 32-39, the flipping wand 44 includes a vertical support member 630 with an upper portion 656 that defines the coupling arm 592 and a lower portion 658 that extends to a substantially horizontal flipping portion 632 that includes a bottom surface 634 that slidably rotates over the cooking vessel base 352 (shown in FIG. 12) and a top surface 636 that includes a proximal portion 638, an intermediate portion 640 and a distal portion 642 where the height of the intermediate portion 640 is less than the height of the proximal portion 638 and the distal portion 642. The height of the distal portion 642 is greater than the height of the proximal portion 638. The coupling arm 592 is disposed at the upper portion 656 of the vertical support member 630. The second end 600 of the coupling arm 592 couples to a curved realignment member 644 that connects the coupling arm 592 to the lower portion 658 of the vertical support member 630, and orients the lower portion 658 of the vertical support member 630 within the rotational axis of the tool impeller 518 (FIGS. 19 and 20). The lower portion 658 couples to the substantially horizontal flipping portion 632 proximate the distal portion 642.

As illustrated in FIGS. 32-39, the substantially horizontal flipping portion 632 of the flipping wand 44 defines a substantially arcuate leading edge 646 disposed proximate the bottom surface 634. A tapered flipping surface 648 is defined by the substantially horizontal flipping portion 632 where the tapered flipping surface 648 extends from the bottom surface 634 to the top surface 636. The tapered flipping surface 648 includes a first flipping angle 650 proximate the proximal portion 638, a second flipping angle 652 proximate the distal portion 642, and a third flipping angle 654 proximate the intermediate portion 640. The third flipping angle 654 is less than the first and second flipping angles 650, 652 and the second flipping angle 652 is less than the first flipping angle 650. As illustrated, the first, second, and third flipping angles, 650, 652, 654 are 62.8 degrees, 49.8 degrees, and 38.8 degrees, respectively. In addition, the selective engagement of the flipping wands 44 within the first and second tool receptacles 542, 544 defines the first and second mixing zones 370, 372 within the first and second wells 24, 26 wherein the first and second mixing zones 370, 372 at least partially intersect within the intermediate necked portion 22 (shown in FIG. 9).

In an alternate embodiment of the flipping wand 44, the coupling arm 592 extends horizontally from the first end 596 to the second end 600 that couples with the upper portion 656 of the vertical support member 630. The vertical support member 630 extends from the upper portion 656 coupled with the coupling arm 592 to the lower portion 658 that is coupled to the substantially horizontal flipping portion 632 distal from the distal portion 642.

As discussed above, in various alternate embodiments, the configuration of the first, second and third flipping angles 650, 652, 654 can vary such that the second flipping angle 652 can be greater than or equal to the first flipping angle 650 and the third flipping angle 654 can be greater than or equal to the first or second flipping angles 650, 652, or both.

Referring once again to the illustrated embodiments, as best illustrated in FIGS. 40 47, the combination wand 590 includes the substantially vertical stirring portion 602 of the stirring wand 42 and the substantially horizontal flipping portion 632 of the flipping wand 44. The substantially vertical stirring portion 602 is configured to slide along the first or second rounded ends 18, 20 of the cooking vessel 14 and the substantially horizontal flipping portion 632 includes the bottom surface 634 that slidably rotates over the cooking vessel base 352 (shown in FIG. 12) and the top surface 636 that includes the proximal portion 638, the intermediate portion 640, and the distal portion 642, where the height of the intermediate portion 640 is less than the height of the proximal portion 638 and the distal portion 642. The height of the distal portion 642 is greater than the height of the proximal portion 638. The combination tool 590 further includes a coupling arm 592 having a first end 596 that is configured to selectively engage the first or second tool receptacle 542, 544 (shown in FIGS. 19 and 20), and a second end 600 that is configured to connect to the upper end 606 of the substantially vertical stirring portion 602.

Additionally, as shown in FIGS. 40-47, the substantially vertical stirring portion 602 includes the tapered stirring surface 610 defined by the first pitch angle 612 proximate the upper end 606 and the second pitch angle 614 proximate the lower end 616 of the substantially vertical stirring portion 602.
